Patent DE-2329902-A1 (DE)
Title: Double acting hammer forge - with minimum shock transmission to frame
Inventor: WOJZECHOWSKIJ BOGDAN WJATSCHES
IPC: B21J7/28
Filed: 1973-06-12
Abstract: The drive for the hammer rams consists of two opposed displacement direction cylinders and plungers and a return mechanism. The two parts of the drive move in a short path in the direction of the hammer rams during the accelerative step. One of the hammer rams is joined by connecting rods with the drive. These rods transmit both the accelerative force to the ram and the subsequent uncoupling of the system comprising the hammer ram and the movable drive member to permit free movement of the hammer ram after acceleration. The other movable part of the drive contacts the other hammer ram to transmit to it the accelerative force, contact being broken once this has been done, whilst the kinetic energy of the two drive members is damped independantly.

Title: Digital determination of frequency analogue measurements - involves use of tranducer, clock frequency generator, gate circuit and digital counter
Inventor: MEYER-EBRECHT DIETRICH DIPL IN
IPC: G01R23/10
Filed: 1973-09-14
Abstract: The transducer converts a measured value to a corresponding first frequency and the generated output frequency is subtracted from the first frequency after dividing it in a frequency divider. The measured values are digitally displayed by the counter. An additional generator supplies a low, variable frequency as compared with the clock frequency. The low, variable frequency is subtracted in an additional subtraction stage from the clock frequency before the latter is divided. The gate circuit is controlled by the voltage, which is derived from the clock frequency generator by the division. The equidistant accuracy is considerably increased by this device.

Abstract: The wire stripping system for the prodn. of composite coil bars consists of a pair of clamping jaws (10) which move along rails and draw the wire (11) between the spray heads (2) and cutting jaws (20). The initial drawing speed is high until a given length has passed through the spray chamber. The speed is then reduced and the spray jets brought into operation. After a given length has been stripped of its insulation the jets are switched off and the speed once more raised to its initial level. After a further given length has passed through the chamber the cutting jaws are operated.
